Making a mining pool/ ticker data app for multiple cryptocurrencies

I am working on a mobile app for Android and iOS that so far supports BTC, LTC, and NMC. I would like to add PPC to the app but I am afraid that there are not enough reliable exchanges and pools yet.

Is anybody interested in something like this?

For exchanges I’ll use:

For pools:
-cant use coinotron, they have no API - I did email them to see about setting one up.
-bitparking is closed now…
-Are there others?

Here are some screenshots so far:

I’m a little tempted to remove NMC and add PPC. Good idea? Would anyone use it?
